In the definitions there is throughout a certain degree of 
vagueness, or at least the absence of that finicalness, which 
is so pleasing to the practical systematist : and in the value 
of the characters chosen to separate the orders and families 
there is great inequality. Hydra and Corine, for example, 
are more nearly allied to Tubularia and Sertularia, than 
the latter are to the Ceratophytes, yet these are placed in one 
and the same, and the Hydra in a separate order. Had the 
Ceratophytes been elevated to the rank of an order, and the Ma- 
drepora been removed to the Polypes cliarnus , the system would 
have been improved, and no very obvious alliances broken. In 
the subordinate parts of the system there are many misplace- 
ments of the subgenera, as the genera of his contemporaries were 
named, of which we may instance the Campanularia which is 
placed under Tubularia of Linnaeus, to which, however, it has 
certainly much less affinity than to the Sertularia, where it had 
always hitherto been assigned. 
In 1810, Lamouroux of Caen presented to the Academy of 
Sciences of Paris a new classification of the flexible polypidoms; 
and it would appear that Lamarck was engaged at the same time
